Inconsistent toe shape – Case #606

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: inconsistency in toe shape from size to size since there were no sizes’ identification marks in the toe moulding machine.

Impactiva solution: we got the factory to prepare jigs for all sizes and placed them on the platform of the toe moulding machine. In this way the artisans can follow the corresponding marking and achieve a consistent toe shape in all sizes.

When Quality Control is not enough – Case #03

This is the last blog of this series for the time being, with real photos taken at final QC inspections of different styles, clients and factories. We will show aesthetic and functional defects, and sloppy rework attempts.

The purpose is to show that when this kind of defects make it all the way to the final QC stage, there is an urgent need to shift from Quality Control to Quality Assurance. This means to focus on quality all the time the product is being manufactured to elevate the outgoing quality, instead of just controlling the result when it is time to ship the goods.

Quality pays for itself. If we calculate the materials, labour, energy and time wasted in producing these shoes that are completely un-shippable, is clear why we say that Quality is free.

When Quality Control is not enough – Case #01

We will post a series of blogs with real photos taken at final QC inspections of different styles, clients and factories. We will show aesthetic and functional defects, and some sloppy rework attempts.

Visible pen marks – Case #605

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: silver pen marks visible on the sole feather edges, which are difficult to clean after glue application.

case 605 pic 1 impactiva footwear qa

case 605 pic 2 impactiva footwear qa

case 605 pic 3 impactiva footwear qa

Impactiva solution: we got the factory to place a 1.0 mm. thick insole board inside the cavity of the sole used for marking. In this way the markings will be done 1.0 mm higher and since the production soles do not have the insole board, the markings will get hidden below the sole wall when attached.

Wrinkles on side quarters – Case #604

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: wrinkles on both side quarters.

case 604 pic 2 impactiva footwear qa case 604 pic 1 impactiva footwear qa

Impactiva solution: we got the factory to use a plastic string on the first eyelet to fasten it tight while passing through the heat setter machine and avoid wrinkles.

Wrinkles on the top line – Case #603

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: wrinkles on the top-line, above the toe-puff area.

case 603 pic 1 impactiva footwear qa

Impactiva solution: we got the factory to attach two pieces of backer cloth up to the folding area, do a 8 mm. taper skiving and use 20 mm. nylon tape below the top line to prevent wrinkles and looseness.

Top lifts – Case #602

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: top lift opens with little pressure as no glue was applied on the stems.

case 602 pic 1 impactiva footwear qa

Impactiva solution: we got the factory to apply adhesive on the three stems to strengthen the attachment and this improved the top lift pull strength.

Thick raw edges – Case #601

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: PU material raw edges look thick and dark, which affects the aesthetics of the shoe.

case 601 pic 1 impactiva footwear qa

Impactiva solution: we got the factory to hammer the raw edges at 3 different stages (component, upper and after lasting) and this way got fine raw edges.
